I've always thought this. But I think "Set of two" could work if you changed the rankings from wins based to point based like football for example lets take a match-up G2 vs FNC:
G2 2-0 FNC - Because G2 won they recieve 3 points and FNC receive 0 points
G2 1-1 FNC - G2 and FNC tie the games and both teams receive 1 point
G2 0-2 FNC - The reverse of the first example so the reverse happens. G2 lost and receive 0 points where FNC receive 3 points.
The system could easily work and make "ties" feel less bad. Its the same in football when a team gets goals enough to ties you fought back to bring the game to that point and are rewarded. And when you win you receive a bigger bonus of 3 points. 2 points wouldn't work as its not a big enough 'bonus' for the win.
EDIT: turns out its been too long since the b02 and i cant remember shit
